What treatment works well for chickens that crane their heads back to look at the sky and kneel on the ground?

During the production process of @#@230@#@, you will often come across some chickens with strange, bizarre postures: the first is the head tilted backward, with both eyes looking up at the sky. The second is walking while kneeling on the ground. What disease are these two postures in chickens a sign of, and what methods are used to treat them?

The first strange posture: head tilted backward, both eyes looking up at the sky. It is a sign that the chicken has VB1 deficiency. VB1, also known as thiamine, is a substance essential for carbohydrate metabolism in the chicken's body. Nervous tissue relies on the oxidation of carbohydrates to supply energy; if VB1 is deficient, then because of insufficient energy supply to its nervous tissue, nutritional disorders of the nerves will appear, leading to functional imbalance, and the sick chicken will show multiple neuritis. VB1 deficiency also slows the chicken's intestinal peristalsis, relaxes the intestinal wall, reduces appetite, and stunts growth. VB1 deficiency can occur in chickens of all ages, but chicks and young chickens are affected more often. Sick chickens have weakness in both legs and an unsteady gait; because of inflammation of the peripheral nerves, the head bends extremely backward, in a shape that looks like gazing at the sky. Prevention and treatment: First, supply enough VB1 in the chicken's diet; adding 0.8 to 0.9 mg per kilogram of feed for young chickens and adult chickens, and 1.5 mg per kilogram of feed for chicks, can prevent the occurrence of this disease; second, for chickens already affected, intramuscular injection of 5 mg of thiamine (the amount for one chicken), once a day, for five to seven consecutive days, gives an extremely good therapeutic effect.

The second strange posture: the chicken walks while kneeling on the ground, that is, when walking it rests on its hocks, with both wings spread out, like an acrobat walking a tightrope, in order to maintain body balance. This is a sign that it has VB2 deficiency. VB2, also known as riboflavin, is a component of many enzymes involved in oxidation-reduction reactions in the chicken's body, and is closely related to the metabolism of protein, fat and carbohydrates. VB2 also plays an important role in regulating cellular respiration and oxidation-reduction; if it is deficient, it will affect the normal progress of biological oxidation, causing metabolism in the body to be impaired. Besides the strange walking posture, another main sign of VB2 deficiency in sick chickens is that the toes curl inward and draw up. Prevention and treatment: First, adding an appropriate amount of yeast, skim milk, alfalfa meal and so on to the chicken's ration can prevent the occurrence of this disease; second, for chickens already affected, add 4 mg of VB2 per kilogram to their feed and feed continuously for seven to fifteen days, which can achieve a relatively good therapeutic effect.
